Smash was a smash with admirers when it opened a year ago, but the bloom soon wore off. In the long pantheon of cautionary TV tales in which series don’t always live up to the promise of their first episode, Smash stands in a league of its own.

Liza Minnelli will guest star on an episode of TV musical drama Smash, NBC said on Tuesday.
The singer and actress will play herself and sing a number in one episode of the show when it returns in February 2013.
